The good news is that you can maximize availability and prevent website crashes by designing websites specifically for these events. There are also online optimization tools available like Tinify , as well as advanced image editing software like Photoshop or GIMP : Image format is also a key consideration. Lets jump right in!
Performance Game Changer: Browser Back/Forward Cache. Performance Game Changer: Browser Back/Forward Cache. With that caveat out of the way, let’s get to the guts of the article: What is the Back/Forward Cache and why does it matter so much? Didn’t The HTTP Cache Do All That Anyway? Barry Pollard.
The code below illustrates how to use WeakSet() and some of the methods available: const human = new WeakSet(); let paul = {name: "Paul"}; let mary = {gender: "Mary"}; // Add the human with the name paul to the classroom. let smashing = {name: "magazine"}; let arr = [smashing]; // Overwrite the reference. It cannot be looped through.
You can find a comprehensive Beginner’s Guide To Progressive Web Apps on Smashing Magazine that focuses on building the core of PWAs. The service workers enable the offline usage of the PWA by fetching cached data or informing the user about the absence of an Internet connection. Cached content with IndexedDB. Service Workers.
Smashing Magazine, like most publishers, makes use of web fonts and the below screenshot shows the difference between the initial render (with the fallback fonts), and the final render (with the web fonts): Smashing Magazine article with fallback font and with full web fonts. Large preview ). Large preview ).
We’ve explored the concepts behind headless CMSes in detail here on Smashing Magazine, but let’s do a quick recap. But where do they preview the content before it is made available to the general public? A preview feature must be available in the pricing plan you have chosen for the headless CMS of your choice. Content Previews.
Now there’s a massive range of Jamstack CMSs available, which bring all the advantages of static sites while allowing non-technical folk to update content. I vividly remember receiving a PC Magazine for my birthday with a trial of Dreamweaver. Smashing Magazine powered by Netlify. MovableType really was before its time.
That user preference is available in two (hopefully soon to be three!) This is available behind a flag in Chrome, but not yet on by default while it finishes standardization. Approximately two-thirds of Indian mobile Chrome users of Smashing Magazine have this setting turned on, for example. Save Data API. And Is It Used?
Without build optimizations (incremental builds, caching, we will get to those soon) this will eventually become unmanageable as well — think about going through all images in a website: resizing, deleting, and/or creating new files over and over again. The cache is invalidated on a time basis. Creating an On-Demand builder.
On top of this foundation, we add layers of caching, prerendering and edge delivery optimizations — not the other way around. Surveying the existing landscape of available developer tools and runtimes, we felt that there is a gap. Large preview ). This is not a debate about dynamic vs. static. You need both.
It allows developers to define, handle, and make queries/mutations available within our application. We’ll be learning how to do this with GraphQL Features like Cache Update, Subscriptions, and Optimistic UI. Updating the cache directly using update function on the useMutation. Then we go to our index.js to import and use it.
Browser Caching. Another built-in optimization of Google Fonts is browser caching. As the Google Fonts API becomes more widely used, it is likely visitors to your site or page will already have any Google fonts used in your design in their browser cache. All of the fonts files are available on Github. Limit Font Families.
Webpage performance test report for the Smashing Magazine website. Cache Your Images. A website’s performance can suffer if frequently accessed images are not cached, as many requests will be made to images that have already been loaded in the user’s system. Large preview ). The Relation Between Images And Web Performance.
Search Engine And Web Archive Cached Results. Another common category of imposter domains are domains used by search engines for delivering cached results or archived versions of page views. Typically, these would be pages that might no longer be available on the site but are available in third-party archives.
MB , that suggests I’ve got around 29 pages in my budget, although probably a few more than that if I’m able to stay on the same sites and leverage browser caching. There’s a trade-off to be made here, as external stylesheets can be cached but inline ones cannot (unless you get clever with JavaScript ). Let’s talk about caching.
By stepping back and realizing that the fields available have no special bindings to particular types of data, we can see that this technique is also an effective delivery mechanism for any arbitrary data allowing lots of interesting possibilities. Here are a few that come to mind: Is this request served from the service worker cache?
These numbers are based on first-page load — caching seems very efficient for subsequent page loads. navigator.share({ title: 'Smashing Magazine', text: 'Web development news and tutorials', url: '[link] }). Two embeds. Description. JS (uncached). Single embed. Two embeds. and simpleshare.io are two of them.
The solution used in Scrapbook was to use the SWR library of React hooks to update the cached page from the server with client side data fetching. The client is first served the cached statically generated page (generated with getStaticProps() ), in the background the server also begins the process of revalidating that page (read more here ).
Inspired Design Decisions: Avaunt Magazine. The flex-grow property with its value of 1 ensures all images expand to fill any available space, while flex-basis makes sure these flex items start from a minimum of 640px; header svg { flex-grow: 1; flex-basis: 640px; } header svg:not(:last-of-type) { margin-right: 2rem; }.
There are various performance budgeting products and open-source tools available, but we decided to create our own custom budgeting service called Perfer. Moving computations from the browser to a backend service can reduce JavaScript download size, increase computation speed, and potentially cache the results for faster reuse.
So, to improve the TTFB, we need to speed up that process or cache the HTML so we can skip the HTML generation entirely. Large preview ) Conclusion Having more granular metric data available for the Largest Contentful Paint gives web developers a big leg up when making their website faster. Sign up for a free trial.
Let the web developer handle all of the necessary speed optimizations like caching and file minification while you take on the following design tips and strategies: 1. You can see in his example that he suggests a number of optimizations, like limiting which styles and character sets are available for use on the website. Minification.
It may even be something you do regularly with Lighthouse in Chrome DevTools, where testing is freely available and produces a very attractive-looking report. CrUX is what fuels PSI and Google Search Console, but it is also available in other tools you may already use. Can’t be perfect every time!
If you haven’t heard, INP is replacing the First Input Delay (FID) metric, something you can read all about here on Smashing Magazine as a guide to prepare for the change. There’s network timing, navigation timing, resource timing, and plenty of custom reporting features available on top of the Core Web Vitals we’ve looked at.
Nx is an open-source build framework that helps you architect, test, and build at any scale — integrating seamlessly with modern technologies and libraries, while providing a robust command-line interface (CLI), caching, and dependency management. Nx uses distributed graph-based task execution and computation caching to speed up tasks.
Today, we’ll address storing and serving files for both single-server and scalable deployments while considering factors like compression, caching, and availability. Performance And Availability. If you’re using a library provided by a third-party CDN, make sure you’re using the minified version of that library if available.
When requesting data from the client-side, it is important to be mindful of a few things: the user’s network connection: avoid re-fetching data that is already available. how to handle when data is not available (server error, or no data). zero-config caching layer. what to do while waiting for the server response.
This approach was touted to be better for fine-grained caching because each subresource could be cached individually and the full bundle didn’t need to be redownloaded if one of them changed. Upon receipt of a valid Alt-Svc header indicating HTTP/3 support, the browser will cache this and try to set up a QUIC connection from then on.
But this “look” is now available in browsers. Due to the use of modern frameworks, advanced caching and rendering, and data transmission via API, properly developed PWAs can be a seven-league step up to boost the store’s speed. A PWA, on the other hand, is available from the browser at all times. Large preview ).
Jump to the workshops ↬ Using CDN For Caching And WebP For Lighter File Sizes As I mentioned a little earlier, our stack includes Sanity’s CMS. It offers a robust content delivery network (CDN) out of the box , which serves two purposes: (1) optimizing image assets and (2) caching them. Let’s see the query caching in action.
It also opens up the possibility for more effective use of caching strategies, potentially enhancing load times further. Their primary role is to store (or “cache”) copies of web content — like HTML pages, JavaScript files, and multimedia content — and deliver it to users based on their geographic location.
Instead, use the measurement tools available to analyze the performance of your React app and get a detailed report of what might be slowing it down. and react-native 0.57+, enhanced profiling capabilities are available in developer mode using React Developer Tools Profiler. Measuring Performance. React Developer Tools Profiler.
In this screenshot below, for example, we can see that loading the Smashing Magazine website for the first time incurs just under a megabyte of data transfer. I predominantly use Nginx, and I have a particular fondness for FastCGI cache and have found it to be especially efficient. Large preview ). We should use HTTP2 over HTTPS.
This video game-like environment goes through the service worker lifecycle, intercepting requests, working with caches, and more. There are plenty of other interactive learning tools available, and I’m sure many of you have come across some that you’ve found useful. Image source: Service Workies ). Learn Git Branching. Quick Summary.
The most popular, by far, is the Google Lighthouse report (available in Chrome Developer Tools) and Google’s Page Speed Insights. You can adjust what browser is used, the kind of network connection to employ, the locations to test from, whether or not the browser’s cache is empty or full, how frequently to take the measurements, and more.
The web is streaming, meaning it has none of the resources locally available when you open an app for the first time. The main thread is responsible for rendering the DOM (via preact and, if available, WebGL) and capturing UI events. 2021-06-30T12:00:00+00:00. 2021-07-13T02:07:04+00:00. Large preview ). The Future.
I think this information is both interesting and useful, in particular given the wide variety of framework and platform choices currently available to front-end and fullstack developers. I assume that caching, both in the browser and CDNs, contributes to this as well.
We can use 11ty’s new Serverless mode to build them on request using Netlify’s On-Demand Builders to cache each Madlib. For example, an “On-Demand Builder” is a serverless function dedicated to serving a cached file. Netlify then caches that page on its edge CDN for each additional call. Large preview ). More after jump!
Specifically, some icons change between the two platforms, app bar titles are in the middle on iOS and on the left on Android (on the left of the available space in case there is a back button or the button to open a Drawer ( explained here in the Material Design guidelines and also known as a hamburger menu). Large preview ).
Partytown works with any HTML page and doesn’t require a specific framework, but there are a few integrations (plugins/wrappers) available, including for Next.js, Nuxt.js, React, and Shopify Hydrogen. document.write() ) known to be harmful to the user experience; Excessive DOM elements or expensive CSS selectors.
So, to improve the TTFB, we need to speed up that process or cache the HTML so we can skip the HTML generation entirely.

Instead, use the getter function because it can be mapped into any vue component using the mapGetters behaving like a computed property with the getters result cached based on its dependencies. It is considered best practice not to directly access a state object. Using the Provide/Inject Method To Pass Data Around.
However, many other devices are sitting between the client and the server that also have their own TCP code on board (examples include firewalls, load balancers, routers, caching servers, proxies, etc.). This all means that QUIC will probably never be universally available, which we’ll discuss more in part 3 ( coming soon! ).
Hence, the API can be implemented on any language (which is one of the beauties of GraphQL: being a specification and not an actual implementation has enabled it to become available in a myriad of languages.). Native Client-Side Cache/Data Store. API response example. We can benefit from this situation in several ways.
